Can anyone confirm this issue?

Well, that's interesting. I assume you're using a hood or didn't you actually shoot these?

No, I didn't shot them but looks like a very ugly issue coming up here...

I'm not noticing any abnormal internal reflection issues with my 750 when I shoot into the light. Guess I'll have to experiment.

I just took a couple of test shots and haven't noticed this issue at all. Not worrying about it.

here we go.

This is not a lens flare... Have you seen this video?

I shoot a lot against the sun, so to me it may be an issue as well as many wedding photographers...

Can you add arrows to the image to show what you think is an internal reflection hitting the sensor?

These 2 images shot about 5 years ago showing that lens flare is totally different issue and may be used to add some dramatic effect...

Look at the original post links... As well as mentioned video... It adds that ugly white blow/line at the top of the image... And this is not the lens flare... This is just not funny especially if you shoot the couple walking from the lower point of view against the sun:-(

Something like these...

To me it is not, especially this: https://secure.flickr.com/photos/emilyporter/15578010509/

Circle - oh yes... Sometimes I even like them... But not the line like these... Well, I may be wrong, but lets see what is going to happen next... LOL...

Sorry.  Have to dismiss all of it.  Get more credible evidence with specific shooting parameters before asking if anyone can "confirm this issue".  A combination of lens flare...  a crappy UV filter...  any number of things could cause the issues you want to point out.  The least likely issue is some "internal reflection" that you seem to be implying Nikon let slip by their QC.

Very well may be, but those lines don't look like lens flares to me...

And BTW: don't kill the messenger... I just asked a question if anyone who owns D750 can confirm this issue reported in NR... Some of the NR readers confirmed it in their comments there...

I agree. Too may weird causes of lens flare that re difficult to repeat. I worked in a pro photo lab for 10 years and saw a lot of funny things happen with optics and reflections of many kinds and I can say with certainty that once the source of the reflection was found and fixed it was easy to see what was causing it and correct it. So if the camera mirror box has a smooth surface no matter how small one should be able to find it and cover it and confirm the problem is gone then publish the exact cause.

I still wonder why the video creator uploaded it at 360p and not at 1080p?

Well, I started out with a box camera, the Ansco Shur-Shot more than 65 years ago and have been shooting images ever since. In film, I've owned and shot with 3 TLRs, 3 Leicas, 3 Retinas, a Nikon Ftn and a Nikkormat, a Nikon S3, a large handful of miscellaneous 35mm cameras, and a couple of digital canon compact advanced point-and-shoots, and many of the Nikon Ds, specifically the Ds80, 200, 300, 700, and now the D750, but I've only used the latter for the last week or ten days, so this old fogey hasn't had much time to experience these so-called "reflections", having waited until yesterday to install my LR 5.7 and make my initial image imports thereto.

I've not seen the reflections so far but I haven't been able to not notice the photgraphic fads coming and going over these many years; in fact, the internet and its many blogs and forums provide an essentially unlimited number of photographs to view and review. The preoccupation with bokeh is hanging in there quite well as is the slow-shutter treatment of falling and other moving water, which reminds me greatly of how Arthur Penn's slow-motion frames of the Tommy-gunning at the conclusion of Bonnie and Clyde got many filmakers to film violent action in slow motion for many years thereafter, and, of course, the frequent attempts of photographers to shoot into or nearly into the sun and then complaint about glare.

We did learn some basic stuff way back then about not shooting into the sun or at the sun from an oblique angle, and when we graduated to interchangable lens cameras we learned to be pretty disciplined about using lens hoods all the time to discourage not only direct light outdoors and even ambient light indoors from cutting contrast in our images. Which is not to say I've not made a few backlit shots (very carefully) and used flash fill foe people shots where either the people or the sun would not move for my convenience.

So I'll make some reasonably comprehensive test shots--but with lens hood present and not into the sun--before I demand a D750 replacement, or hope for a D760, or buy a Holga or a damaged 35mm camera to effectively capture any light leaks that happen my way.

Happy shooting.

Where I lose patience is the point where we've already defined this as an issue.  I'm not trying to shoot the messenger except when the messenger has already categorized this as an issue.  From the posted photos all I've seen is a bunch of photos shooting into extreme light.  Do you have any samples at all where the scene was shot with two different brand cameras?  Until then there is no "issue".

Dude, that's lens flare.
